COCKLE-SEED SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 318,677, dated lflay 26, 1885.

Application filed October S, 18524.

To all whom it natty concern:

Be it known that I, GEORGE ADAMS, of Sherburne, in the county of Martin and State of Minnesota, have invented certain new and useful Improvements in Cockle-Seed Separa tors,of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of my improvement. Fig. 2 is a plan view of the same, parts being in section. Fig. 3 is a side elevation of two of the chain-wheels, a portion of the driving-chain, and atension-pulley, the journals of the rollers being shown in section. Fig. 4c is a front elevation of one of the tension rollers and its support.

The object of this invention is to facilitate the removal of cockle-seed from wheat.

The invention consists in a coekle-seed separator constructed with a series of rollers having face-indentations and corrugated end wheels, a series of plates interposed between the rollers, and having end plates provided with toes to engage with the said end wheels, a series of springs for holding the plates down, a series of guard-springs attached to the plates and resting. against the said rollers, to prevent the indentations from carrying out small kernels of wheat, and a series of chain-wheels attached to the roller-journals and provided with an endless chain,held down upon them by tensionrollers pivoted to bent bars attached to the machine-frame, whereby the coekleseed will be separated from the wheat as it passes through the machine, as hereinafter described and claimed.

A represents the frame of the machine, which may be the frame of an ordinary fan-mill or a frame built especially for this machine.

In bearings in the inclined side bars of the frame A are placed the journals of a series of small iron rollers, B, in the surfaces of which are formed numerous indentations, 0, arranged in annular rows and of such a size as to receive cockle-seed and other round seed.

Between the rollers B are placed plates D, the edges of which are close to the said rollers B.

(No model.)

To the ends of the plates D are attached plates E, the upper or rear ends of which are perforated to receive and ride upon the j ournals of the preceding rollers, B.

The forward ends of the plates E have toes F formed upon them to rest upon the corrugated wheels G, formed upon or attached to the end parts of the rollers B, so that the said plates D will be agitated to feed the grain forward by the revolution of the said rollers B. The upper plate, D, which serves as a feedapron to receive the grain from a hopper or spout and deliver it to the machine, is supported at its upper edge by a spring, H, at tached to the frame A.

To each plate D are attached springs I, which are bent rearward, downward, and forward, so that their free ends will rest against the forward sides of the rollers B at each circle of indentations in said rollers B, to prevent any small kernels of wheat from being carried by the said indentations between the rollers B and the edges of the plates D. The free ends of the springs I are widened and forked, as shown in Fig. 2, so that cockle-seed and other round seeds can pass the said springs, while the oblong wheat-kernels will be thrown out.

The plates D are drawn downward, holding the toes F of the end plates, E, against the corrugated wheels G, so as to make the jarring of the said plates more positive, by springs J, the upper ends of which are attached to the under sides of the said plates D, and their lower ends are attached to the inclined plate K, or other suitable support. The plate K is attached to the frame A below the rollers B, to receive the cockle-seed and conduct it out of the machine. The wheat as it passes the last roller B falls into a spout, L, and is conducted out of the machine.

Brushes M are attached to the plates D, to rest against the rollers B and clear the indentations O as the said rollers revolve.

The journals of the rollers B upon one side of the machine proj ect, and to them are attached chain-wheels N, around which passes an endless chain, O. The chain 0 is held down be tween the chain-wheels N by rollers P, to hold the said chain in gear with the said chainwhcels. The rollers P are pivoted to the up- ICO per ends of the bars Q, the lower parts of which are bent inward and then downward, and their lower ends are attached to the frame A.

The other journal of the upper roller B pro- 5 jects, and to it is attached a pulley, It, or a fast pulley, R, and a loose pulley, S, to receive a driving-belt from the driving mechanism of the fan-mill or other convenient power.

In using the machine, as the grain passes down, the cockle-seeds enter the indentations O of the rollers B, and are carried down past the edges of the plates D, are dropped upon the inclined plate K, and pass out of the machine.

In case any of the cockle-seeds are too large to be wholly beneath the surface of the rollers B, they will be split or crushed by coming in contact with the edges of the plates D, the parts of the said seeds remaining in the indentations being carried down and dropped to the plate K, While the other parts of said seeds will pass down to the next roller, and will be taken out by its indentations.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. A cockle-seed separator constructed sub stantially as herein shown and described, and

consisting of a series of rollers having indentations and corrugated end wheels, a series of plates interposed between the rollers, and havo ing end plates provided with toes, a series of springs for holding the plates down, a series of guard-springs to prevent the indentations from carrying out small kernels of Wheat, and a driving mechanism, as set forth.

2. In a cockle-seed separator, the combination, with the rollers B, having indentations G, and the interposed plates D, of the bent springs I, having forked ends, substantially as herein shown and described, whereby the said 0 indentations will be kept from carrying out small kernels of wheat, as set forth.

3. In a cockle-seed separator, the combination, with the frame A and the rollers B, of the chain-wheels N, the endless chain 0, the 5 tensionrollers P, and their supports Q, substantially as herein shown and described, whereby the said rollers will be revolved together, as set forth.
